New insights into yeast cells may help identify cancer cells and stem cells development: Study

Yeast cells decide whether to have sex with each other within two minutes of meeting, according to new research published today in Nature. One of the authors of the study, from Imperial College London, says the new insights into how yeast cells decide to mate could be helpful for researchers looking at how cancer cells and stem cells develop.

Enhancing drug residence time may help develop better diagnostic, therapeutic agents

Research conducted at the Stony Brook University Institute for Chemical Biology & Drug Discovery that enhances the time a drug remains bound to its target, or residence time, may prove to be an important step in developing better diagnostic and therapeutic agents based partly on longer drug residence time.

Marker found in iPS cells correlates with levels of pluripotency: Researchers

Researchers in China are reporting that they have found a way to determine which somatic cells -- or differentiated body cells -- that have been reprogrammed into a primordial, embryonic-like state are the most viable for therapeutic applications.

Study links cancer growth to sugar-based modification found naturally in the body

Researchers at Drexel University College of Medicine have discovered that a certain type of sugar found naturally in the body is elevated in breast cancer cells and is critical for cancer growth and movement. When researchers reduced and normalized the levels of this sugar, they were able to slow the growth of the cancer cells and block invasion. The findings, published in the March 1 issue of Oncogene, represent a potential new therapeutic target for treating aggressive forms of breast cancer.

Celgene, Agios Pharmaceuticals form global strategic collaboration on targeting cancer metabolism

Celgene Corporation and Agios Pharmaceuticals Inc., a privately-held biotechnology company, today announced the formation of a global strategic collaboration focused on targeting cancer metabolism. The goal of the collaboration is to discover, develop, and deliver novel disease-altering therapies in oncology based on the transformational science of Agios' innovative cancer metabolism research platform. This platform is based on the concept that targeting key metabolic enzymes unique to rapidly proliferating cancer cells can "starve" the cancer.

Scientists uncover new genes responsible for cancer, deafness

From deep within the genomes of organisms as diverse as plants, worms and yeast, scientists have uncovered new genes responsible for causing human diseases such as cancer and deafness.

Researchers invent zinc-stapled insulin to reduce insulin-related cancer risk

For millions of Americans with Type-2 diabetes and inject insulin to control diabetes (with onset typically in adulthood) the associated risk of cancer is of increasing concern. Studies have demonstrated that obesity and excess insulin - whether naturally produced by the body or injected in synthetic form - are associated with an increased incidence of some common cancers.

Stress hormones may suppress tumor growth: Study

Chronic stress triggers a chain of molecular events that protects breakaway ovarian cancer cells from destruction, a team of researchers led by scientists at The University of Texas M. D. Anderson Cancer Center reports April 12 in the early online publication of the Journal of Clinical Investigation.

Gilead Sciences doses first patient in Quad Phase III clinical program

Gilead Sciences, Inc. today announced that it has dosed the first patient in the Phase III clinical program evaluating its investigational fixed-dose, single-tablet "Quad" regimen of elvitegravir, cobicistat (formerly GS 9350), emtricitabine and tenofovir disoproxil fumarate.

Researchers report major step forward in effort to understand and engineer protein structure

Researchers in Singapore are reporting this week that they have gleaned key insights into the architecture of a protein that controls iron levels in almost all organisms. Their study culminated in one of the first successful attempts to take apart a complex biological nanostructure and isolate the rules that govern its natural formation.

Scientists identify specific mechanism that triggers resistance to vancomycin

A new study led by the scientific director of the Michael G. DeGroote Institute for Infectious Disease Research has uncovered for the first time how bacteria recognize and develop resistance to a powerful antibiotic used to treat superbug infections.

Ku protein employs unique mechanism for DNA repair: Researchers

Scientists have shown in multiple contexts that DNA damage over our lifetimes is a key mechanism behind the development of cancer and other age-related diseases. Not everyone gets these diseases, because the body has multiple mechanisms for repairing the damage caused to DNA by aging, the environment and other human behaviors - but the mechanisms behind certain kinds of DNA repair have not been well-understood.

Effective compound against antibiotic-resistant biofilms

Researchers at North Carolina State University have found a chemical compound that, when used in conjunction with conventional antibiotics, is effective in destroying biofilms produced by antibiotic-resistant strains of bacteria such as the Staphylococcus strain MRSA and Acinetobacter. The compound also re-sentsitizes those bacteria to antibiotics.

Drugs that affect methylation state of genes could reverse autism's effects: The FASEB Journal

A new discovery raises hope that autism may be more easily diagnosed and that its effects may be more reversible than previously thought. In a new study appearing online in The FASEB Journal, scientists have identified a way to detect the disorder using blood and have discovered that drugs which affect the methylation state of genes could reverse autism's effects.

New methodology helps investigate unfolding of DNA

NYU Langone Medical Center researchers have developed a powerful new method to investigate the discrete steps necessary to turn on individual genes and examine how the process goes wrong in cancer and other diseases. The finding, based on seven years of research and described in the April 9 issue of Molecular Cell, allows scientists to investigate the unfolding of DNA, a process required for gene activation.

Researchers show iRGD peptide increases treatment efficacy against cancer

Researchers have shown that a peptide (a chain of amino acids) called iRGD helps co-administered drugs penetrate deeply into tumor tissue. The peptide has been shown to substantially increase treatment efficacy against human breast, prostate and pancreatic cancers in mice, achieving the same therapeutic effect as a normal dose with one-third as much of the drug.

Single vaccine for anthrax and plague: iBio confirms grant of rights

iBio, Inc. confirmed today the grant of rights to use iBio's proprietary technology, the iBioLaunch™ platform, in support of a $5.3 million government-funded project for the development of a single vaccine to protect against both anthrax and plague. The project will be managed by Fraunhofer USA Center for Molecular Biotechnology (CMB) pursuant to the long-term agreement between iBio and CMB for advancement of the iBio technology.

Study: 75% of men with diabetes will develop some degree of ED

Erectile dysfunction is one of the most prevalent diabetes-induced complications in men; current estimates suggest that as many as 75% of men with diabetes will develop some degree of ED, and in many cases diabetics develop more severe forms of ED that are less responsive to standard drugs.

Cancer research at Georgia Tech: Report

Cancer treatment typically involves surgery, radiation therapy, chemotherapy, hormone therapy or biological therapy. An oncologist may use one therapy or a combination of methods, depending on the type and location of the cancer, whether the disease has spread, the patient's age and general health, and other factors.
